How do you design a perf board layout?

Hello everyone!
I finally have some time to dedicate to the building of stompboxes, so I decided to retry to solder my TS808, since last time it didn't go that good! :D
I redesigned the perfboard layout, and I'm wondering how to join all the ground and the Vc points together... how do you manage this?

Here is my layout:



It is a mess, isn't it? :D Can I improve it in some ways?
Thanks all!

I usually start by listing my 2 or 3 most congested connection points on a piece of paper and start building the layout from from there. I find, if you deal with the traffic jams first, then everything else kind of flows out naturally. However, I've only done 3 perfboard layouts, so I'm hardly an expert.  :icon_wink:

When I perf a project, I put the input on the left side and work towards the right through the schematic.  Top is always +V and bottom is always ground.  That makes it pretty simple to have all the grounds together, though an occasional jumper is used.

+1 on all of that - exactly how I do it. And use DIY Layout Creator - it's awesome.

What I try to do is to use less space I can, and maybe this complicates the layout! :(
Btw, DIY Layout Creator is a very useful software! :)

I love perf and super-tight layouts you can do.
+1 on the left-to-right, topV+, bottomGRND, that's the way I do it! that's so easy when working with transistors!!
Only those who attempt the absurd will achieve the impossible.

Yeah!
I managed to solder my ts808 and it works, this time!
Following the layout I posted above, here's the wiring hell that came out:





My soldering skills are still quite low, but it seems to me I'm making progresses! :)


ayayay!

I agree with all of that.  The one thing I would add is:  Start with your chip(s) first, somewhere that's kind of like the position of it in the schematic, and build out the surrounding components, then blend that in with the left to right schematic approach if possible.  I usually try to allow myself 1 (and only 1) flying wire.  If I can't do that, I typically start over.  That's sometimes hard to do when you've got Vr running all over the place, but I still try.
